The parents of "Star Trek" actor Anton Yelchin are filing a lawsuit against Jeep, alleging defects in their son's vehicle led to his death. Ted Chen reports for the NBC4 News on Tuesday, Aug. 2, 2016. (Published Tuesday, Aug. 2, 2016)

The parents of "Star Trek" actor Anton Yelchin, who died when he was pinned by a rollaway Jeep in the driveway of his Los Angeles home, plan to file a lawsuit Tuesday against the automaker, alleging defects in the vehicle led to his death.

Yelchin, 27, was best known for his role as Chekov in the recent series of "Star Trek" films. He died June 19 at his Studio City home in the 3800 block of Berry Drive, with investigators saying his 2015 Jeep Grand Cherokee rolled backward down his steep driveway, crushing him against a brick mailbox pillar and a security fence.

Police said Yelchin had gotten out of the car when it rolled away. That model vehicle was under recall over concerns about gear shifters confusing some drivers, causing vehicles to roll away unexpectedly.

Fiat Chrysler, which owns Jeep, issued a statement last month saying the company was investigating the actor's death, and it expressed sympathy for Yelchin's family. There was no immediate comment from the company on the planned lawsuit, which will be announced by Yelchin's parents and their attorney, Gary Dordick, at an 11 a.m. Tuesday news conference.

According to Dordick's office, the lawsuit will be filed in Los Angeles Superior Court, but no details will be released until the news conference. Days after Yelchin's death, a group of Jeep Grand Cherokee owners filed a proposed class-action lawsuit against Fiat Chrysler in federal court in Riverside, alleging the automaker concealed and failed to fix a shifter design defect linked to driverless rollaway accidents, such as the one that killed the actor.

The plaintiffs also allege that the "raft of negative publicity" surrounding the recent disclosure of the problem has greatly diminished the resale value of their vehicles. According to the complaint, the defect has been responsible for at least 41 injuries, and possibly caused the death of Yelchin. Fiat Chrysler initiated a recall of 1.1 million cars worldwide equipped with the defectively designed shifter but has yet to provide any fix, the lawsuit states.

Yelchin, who was born in St. Petersburg, Russia, also appeared in such films as "Alpha Dog," "Terminator Salvation" and "Charlie Bartlett."

He was supposed to meet up with friends for rehearsal the day of his death, police said. When he did not show up, his friends went to his home and found him dead by his vehicle. An only child, Yelchin was 6 months old when he moved with his family to the United States in September 1989. His mother worked as a figure skating choreographer and his father as a figure skating coach.
